Researchers behind ‘Anthropocene equation’ say impact of people’s intense activity on Earth far exceeds that of natural events spread across millennia
For the first time, researchers have developed a mathematical equation to describe the impact of human activity on the earth, finding people are causing the climate to change 170 times faster than natural forces.
The equation was developed in conjunction with Professor Will Steffen, a climate change expert and researcher at the Australian National University, and was published in the journal The Anthropocene Review.
The authors of the paper wrote that for the past 4.5bn years astronomical and geophysical factors have been the dominating influences on the Earth system. The Earth system is defined by the researchers as the biosphere, including interactions and feedbacks with the atmosphere, hydrosphere, cryosphere and upper lithosphere.
But over the past six decades human forces “have driven exceptionally rapid rates of change in the Earth system,” the authors wrote, giving rise to a period known as the Anthropocene.
“Human activities now rival the great forces of nature in driving changes to the Earth system,” the paper said.
Steffen and his co-researcher, Owen Gaffney, from the Stockholm Resilience Centre, came up with an “Anthropocene Equation” to determine the impact of this period of intense human activity on the earth

La Niña Update...
Well, that was quick! The ocean surface in the tropical Pacific is close to average for this time of year, putting an end to La Niña, and forecasters expect that it will hover around average for a few months. Let’s dig in to what happened during January, and what the forecast looks like.

Quote of the Week...
As Gavin Schmidt, Director of the Goddard Institute for Space Studies and Principal Investigator for the GISS ModelE Earth System Model, put it, “In science, nothing is ever known perfectly. Is there remaining uncertainty in the exact value of gravity? Yes. But to something like the fourth decimal place. It doesn’t matter. So the question is: Is the remaining uncertainty relevant to any policy decision anyone would want to make? And the answer is: no.”

Canada’s Censored Scientists Are Helping American Researchers Resist Trump by Stephen Buranyi, Motherboard, Feb 9, 2017
The centre is a transdisciplinary initiative between Stockholm University and the Beijer International Institute of Ecological Economics at The Royal Swedish Academy of Sciences. It also offers a Masters programmes on social-ecological resilience and has its own PhD Research school.
Research at the Stockholm Resilience Centre is transdisciplinary but organized within the following areas:
- Adaptive governance, knowledge generation and social networks studies how the different aspects of governance and knowledge groups interact to provide resilience against global challenges.
- Governance of marine systems aims to secure the oceans' ability to continue to provide ecosystem services.
- Governing freshwater works on ways to improve freshwater green water and blue water flows.
- Regime shifts focuses on sudden and often dramatic changes in social-ecological systems and the subsequent reorganization
- Global and cross-level dynamics studies the interactions between human activities and Earth's environment, particularly how local and regional drivers can generate global-scale changes
- Urban social-ecological systems studies the challenges posed by urbanization and the transformation of rural, peri-urban and urban landscapes.
